I have a Dell Inspiron 15r se 7520. I have upgraded my system to Windows 8.1 few days back. After the upgrade, my Intel HD 4000 graphics driver stopped working.

I have downloaded the latest driver from Dell website but during installation it said that my graphics driver is not compatible or validated and also my dedicated graphics driver AMD ATI Raedon HD 7730m also stopped working. There is also a problem with my screen brightness: I am unable to change it.

How to make my graphics driver work?

Please provide the version of the driver you downloaded from Dell. Did it specifically mention Windows 8.1 support? –  Ramhound Oct 28 '13 at 10:04
